Abstract

A magnetic resonance device includes a radiofrequency unit that includes a radiofrequency antenna, at least one radiofrequency line and at least one radiofrequency injection point. Radiofrequency signals are transferred to the radiofrequency antenna by the at least one radiofrequency line and are coupled into the radiofrequency antenna at the at least one radiofrequency injection point. The magnetic resonance device also includes a patient receiving zone that is at least partially enclosed by the radiofrequency antenna, and a motion detection unit for detecting a movement of a patient that may be positioned within the patient receiving zone. At least one radiofrequency line includes at least one injection element by which at least one motion detection signal of the motion detection unit is coupled into the radiofrequency line.
